STUMP-PULLER.

SPECIFICATION forming part of Letters Patent No. 394,155, dated December 11, 1888.

Application filed June 22, 1888. Serial No. 277,901. (No model.)

1'0 all whom it may concern.-

Be it known that we, ALEXANDER P. (OPP and JOHN M. REMALEY, of Rochester Mills, in the count of Indiana, State of Pennsylvania, have invented a certain new and useful Improvement in Stump-Pullers, of which the following is a description suiiicieutly full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference be ing had to the accompanying drawings, forming part of this specification, in which- Figures 1, 2, and are perspective views of our improved stump-puller represented as in use in diiferentpositions, a portion of thedcrrick and lever being shown as broken off in Figs. 2 and 23.

Like letters and figures of reference indicate corresponding parts in the different figures of the drawin Our invention relates to that class of stumppullers which are designed to be operated by hand; and it consists in certain novel features, as hereinafter fully set forth and claimed, the object being to produce a more effective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conbeing secured by one end to the outer end of Versant with such matters from the following explanation:

In the drawings, A represents the framework of the sttnnp-puller, which consists of three legs or standards, a, pivoted by their upper ends in brackets r on a key-block, z, and forming a tripod or derrick for supporting the lifting apparatus, hereinafter described.

A centrally-arranged supporting-bar, C, is suspended by means of a ring or hook, 012, from the key-block z. A horizontally-arranged bifurcated lever, b, is pivoted to the upper portion of the bar C by a bolt, (1. A bifurcated arm or brace, 'z', is secured to the bar C, one member only being visible in the drawings, and pivoted at 45 to said arm is a hand-lever, D, which is connected with the outer end of the lever 13 by a pivoted bar, 71, thereby forming a compound lever. A ratchetbar, H, is fitted to work between the inner end of the arms 1'. Two links, is, are pivoted by their upper ends to the inner end of the lever Z), the free ends of said links being adapted to engage the teeth g on the ratchet-bar II and lift said bar when raised by said lever. The links L: are constructed of different lengths, so that when the lever I), which actuaics the lever Z), is operated said links will engage the ratchet ll alternately. A forked lever having curved arms .9 j is pivoted at (it) to the supporting-bar 0, one arm, 8, of said lever engaging the free end of the short link 7:, and

the other arm en a in the free end of the i, 7 #3 h b long link 7;. A coiled spring, 5 3, is secured by one end to the arm (ii of said forked lever, and a chain, 2', to the outer end of said. spring, said chain being provided with a hook, 55, for securing it to a hook, 57, on the lover I), the purpose of said forked lever, spring, and chain being to disengage the links A from the teeth of the ratchet II when the outer end of the lever I) is elevated, as shown in Fig. 3, during the process of lowering the load, hereinafter described.

Supporting-iinks 1(- are pivoted at one end to the bar 0, their outer or free ends engaging the teeth of the ratchet II. A forked lever having curved arms f g is pivoted at (52 to the bar C, so that said arms will engage the free ends of the links 11', a coiled spring, 54,

the straight arm (32} of said lever. A chain, 3/, provided with a hook, 5H, for securing it to a hook, 59, on the lever l), is attached to the spring 5;, said lever, spring, and chain being designed to disengage the links 11' from the ratchet II when the lover I) is depressed during the process of lowering the load, as shown in Fig. 2. A rod, 15,is detachablysuspended from a hook, 25, secured to the key-block z, and a chain, it upon which disposed a sheave/block, 17, has one end secured in the lower end of the ratchet-bar II, the opposite end of said chain being secured in an eye, 18, on the lower end of the bar 15. A chain, 20, provided with a hook, 21., is secured to the lower end of the supporting-bar C.

In the use of our improvement a chain, 23, is secured to the stump E, and a hook, 24., on the sheave-block 17 inserted in said chain, the derrick A having been adjusted in position over said stump, after which the rod 15 is secured to the key-block .2, as described. The hooks 55 and 56 are detached from the hooks 57 and 55) on the levers b and D and hang suspended, as shown in Fig. 1, during the process of lifting. By depressing the lever D, and thereby elevating the short arm of the lever B, a link, 7.1", pulls the ratchet-bar H upward and gradually tightens the chain 16. As the lever l) is released or raised to repeat the operation, thereby detaching said link from said ratchet, a link 10 holds said ratchetbar in the position it has attained until another link, 7.:, engages it and draws it still farther upward as said lever is again (lepressed.

It will be understood that the links 7t and w are held in engagement with the teeth q of the ratchet-bar ll by their own weight, and by constructing the links 7e 7c of different lengths, as described, they alternately engage a tooth of said ratchet-bar at each downward motion of the lever D,the links it meanwhile supporting said ratchet-bar and preventing it from slipping downward, so that no motion is lost during the interval of raising said lever to obtain a new hold on said bar.

By securing an ordinary grappling-chain to the stump and fastening it to the hook 21 on the chain 20 the stump may be sustained in the position to which it has been elevated when it becomes necessary to attach the chain 23 to some other portion thereof in order to loose the roots.

By employing the rod 15, adjusted as described, a great portion of the lifting strain is transferred from the ratchet-bar H directly to the derrick.

It will readily be seen that by the use of the compound lever D b and the sheave-block 17 sufficient leverage is obtained to overcome great resistance with the expenditure of a very small amount of power.

By distributing the lifting strain as described, so that the ratchet H and supporting.- bar 0 are relieved of a large portion thereof, a much lighter apparatus may be employed to perform the same work than is possible in stump-pullers when constructed in the ordinary manner.

\Vhen it is desired to lower the load raised, as above described,the hooks 55 and 56 are connected, respectively, withthe hooks 57 and 59 on the levers b and D. The lever D,being then depressed, causes the spring 54 to be distended, and thereby forces the curved arms f g of the forked lever 62 against the free ends of the links 10, disengaging said links from said ratchet, as shown in Fig. 2. The lever D being then elevated, as shown in Fig. 3, the ratchet-bar H is permitted to fall several notches before the spring 54 is relieved sufficiently to enable the links at to again engage said ratchet and support the load. By continuing the upward motion of the lever D above the plane of the arm '2- the curved arms 8 j are caused to engage the free ends of the lifting-links 7e and force them out of engagement with said ratchet, as shown in Fig. 3, so that when the downward motion of the lever D is resumed and continued sufficiently to cause the spring 53 to be released said links will again engage said ratchet several teeth above where they were last engaged. By continuing to oscillate the lever D it will be seen that the load will be quickly lowered to the ground, the operation of the links upon the ratchet being diametricallyopposite to that by which the loadis raised.

Having thus explained our invention, what we claim, is

1. In an apparatus of the character described, the combination of the tripod-derrick A,the pendent supporting-bar C, secured to said derrick, the arms 1', secured to said bar, the lever D, pivoted to said arms, the lever Z), pivoted to said bar, the arm 72, pivoted to said levers, the ratchet-bar H, the links 20, pivoted to the bar C, for supporting said ratchetbar, the links la, pivoted to the lever 19 and adapted to alternately engage the teeth of said ratchet and elevate the same, aforked lever pivoted to the bar (J and having the curved arms .9 for disengaging the links k from said ratchet, the spring 53, connecting said forked lever with the lever Z), a forked lever provided with curved arms f g, for disengaging the links 20 from said ratchet, the spring 5%, connecting said forked lever with the lever D, and a chain for securing said ratchet-bar to the object to be lifted, substantially as set forth.
